This letter is the ISAB's response to your January 29, 2001 request for our review of several questions pertaining to the disposition of "surplus" hatchery-reared adult salmon. Since salmon are beginning their seasonal migration into the basin, we are aware of the urgency in receiving our answers. The purpose of this letter is to provide our input to your staff and regional stakeholders as they begin working through the decision process on the individual cases where surplus hatchery-reared adults may occur this season. This letter is primarily concerned with a condensed summary answer to your first two questions.
